Behind the doors of this school lies a world on the sidelines. We watch as five students with mental disabilities, who will have to learn to live together, take their first steps inside. They are so closed off from one another that this seems like a virtually impossible mission. Yet little by little, the class takes shape before our eyes, and its students advance toward and against everything. With humor and tenderness, the adventure of this small group, who are not like other children, opens up to life and to the world.
